Abstract

This article documents the computational methods and theoretical results for the deformable flat plate (DFP), array feed compensation system (AFCS), monopulse tracking system, and combined AFCS-DFP used for compensating the gravityinduced distortions on the DSN’s 70-m antenna. These systems were utilized in an experiment designed to verify gravity compensation and tracking performance of the 70-m antenna at 31.8-32.2 GHz (Ka-band). This experiment took place from November 1998 through February 1999 and consisted of both quasar and spacecraft observations. The theoretical results are compared with the experimental data. The analytical tools are also used to document and understand the characteristics of each system.
